PIPE AND OONDUIT POR CONVEYING LIQUIDS, &c.

Patented Sept. 11, 1883.

'IIIIIIIIIIIIIII into sectionsof any desired length. The joint between the sections or .lengths may be made bya collar, c, Fig. 3, formed of the same compound or of other suitable material, and the spaces lled with asphaltum or like substance or other known or suitable means for making aj oint between lengths of pipe may be adopted.

It is obvious that articles not tubular could be made from the composition of asphaltum or like material and ber by pressing the same through a die by a plunger or piston.

lf the pipe, tube, or conduit is to be made by wrapping sheets ofv the material around a mandrel, the composition may be applied to the strengthening fabric before wrapping. The strengthening fabric may be omitted when it is so desired. It is not necessary that the plastic material be wholly of resinous or tarry matters and bers, since other niaterials-saypowdered minerals on the one hand, or oils and like materials on the other-may be added. Animal as well as Vegetable ber may beV used. 'The pipe may be in straight or in curved lengths, in the form of traps, Y `or T branches, or, in ne, in any suitable form..

Having now fully described my said invention and the manner of carrying the same into effect, what I claim is- 1. A pipe, tube, or conduit for conveying liquid or gas, for containing electrical conductors, or for other purposes, made of or lined or coated with a composition of animal or vegetable ber, mixed with a resinous or tarry material, substantially as described.

2. A pipe, tube, or conduit for conveying liquids or gases, for containing'electrical conduct-ors, or for other purpose, made of a composition of animal or vegetable ber, mixed with resinous or tarry material and wrapped or combined with strengthening fabric, substantially as described.

3. The method of making pipes, tubes, or conduits by mixing animal or vegetable fiber- Wood pulp, for example-with liquefied resinous or tarry material, and then making the composition into tubular forms, substantially as described.

4. A pipe, tube, or conduit for conveying liquids or gas, for containing electrical conductors, or for other purpose, formed of acompressed composition of asphalt or other resinous or tarry matters and animal or vegetable ber, substantially as described.

5. rlhe manufacture of pipes, tubes, conduits,

or other articles by pressing a composition of asphalt or other resinous or tarry matters and wood or other ber, animal or vegetable, through a contracted opening or die, substantially as described.

In testimony whereof I have signed this specication in the presence of two subscribing witnesses. v
